D70 enables experienced-to-amateur photographers to easily adopt digital technology into their existing camera system. The camera has 3D Digital Matrix Image Control, Digital Vari-Programs, and a lens servo system. Nikon engineers chose the MPC17511 H-bridge motor driver IC from Freescale Semiconductor to power the motor. The monolithic driver integrates control circuitry for driving integrated and external n-channel MOSFETs. Designed for PWM control frequencies up to 200 kHz, the analog IC offers increased battery life for the portable application.
